I purchased this for trail running and used it once, but the size didn't fit, so I'm selling it. It has been used, so it's not in pristine condition, and I ask that those who are meticulous refrain from purchasing. I think it's quite light and easy to use. A lightweight and breathable mesh backpack with a front pocket. - Brand: U-Makes - Color: Black - Features: Lightweight, breathable mesh material - Design: With front pocket Thank you for looking.
